The better quality your fishing rod is, the more better loot you get.

To fish.. build a chair, set it where you want to fish. Equip a rod, attach bait "ammo" to rod, put rest in hotbar (I use slot one), cast and wait for a bite. Play mini game to reel fish in. (This was how it worked for me on the PC)

No but fr how do you even apply bait to the fishing rod in ark mobile its pain

You've got to sit on a chair or something

How do you use a stupid fishing rod?

How do you put bait on the rod?
